LeeBoy 3000C - Changing Hydraulic Oil; Changing Hydraulic Oil Strainer

Changing Hydraulic Oil
Changing the hydraulic oil removes the accumulation
of dirt, water and mechanical wear particles from the
hydraulic oil reservoir and system. The chemical
structure of hydraulic oil changes after continuous
use, therefore, new oil is important to ensure correct
operation of the hydraulic system.
Hydraulic oil that has oxidized or
contains contamination can shorten the expected
service life of the components in the hydraulic
system.
Use the following procedures to change the hydraulic
oil:
1. Stop the engine. Allow the hydraulic oil to cool
until it is at a warm temperature. Slowly loosen and
remove the hydraulic oil reservoir ller cap (Figure
5-13). Put a clean, lint-free cloth over the reservoir
ll tube opening and secure in place with tape.
DO NOT drain the hydraulic oil from
the reservoir when it is HOT. Hot hydraulic oil can
cause serious injury. Drain at a warm temperature
only.
2. Carefully remove the plug from the hydraulic
tank. Use a drain collection container of sufcient
capacity to collect the hydraulic oil underneath.
Allow all of the hydraulic oil to drain into the
container.
DO NOT ll the hydraulic oil reservoir
with new hydraulic oil until the suction strainer has
been serviced.
3. Check the hydraulic suction strainer in bottom of the
hydraulic oil tank. Clean if necessary.
4. Install the hydraulic oil reservoir drain plug and
tighten securely.
5. Carefully remove the cloth from the hydraulic oil
reservoir ll tube opening.
6. Rell the hydraulic oil reservoir (recommend Citgo
All Weather/All Temperature Multiviscosity hydraulic
oil).
DO NOT overll the hydraulic oil
reservoir with oil.
Never let tank run dry. Pump damage
will occur.
7. Check the oil level in the hydraulic oil reservoir,
again. Add oil if needed.
8. Replace the hydraulic oil ller cap onto the reservoir
ller neck and tighten securely.
9. Start the engine.
10. Check the hydraulic system for any leaks.
Changing Hydraulic Oil Strainer
The oil strainer is mounted in the hydraulic oil ller
opening under the ller cap. (Figure 5-13)
DO NOT remove the hydraulic ller
cap from the reservoir when it is hot as this can
cause serious injury. Allow hydraulic oil to cool down
to a warm temperature.
To change the hydraulic oil strainer:
1. Remove the hydraulic oil ller cap.
2. Remove the six (6) screws securing the strainer,
then remove the strainer and gasket.
3. Install a new gasket, aligning the six screw holes in
the gasket with the mounting holes on the reservoir.
4. Install the new strainer, aligning the holes in the
strainer with the mounting holes of the gasket and
secure the strainer with the six screws.
5. Fill the hydraulic oil reservoir with (recommend
Citgo All Weather/All Temperature Multiviscosity
hydraulic oil).
DO NOT overll the hydraulic oil
reservoir with oil.
6. Check the oil level in the hydraulic oil reservoir. Add
oil if needed.
7. Reinstall the hydraulic oil ller cap and tighten
securely.
